The text of this paragraph should be normal (that is, it should not be
underlined, overlined, stricken, or bold), because diagonal is not a valid keyword, making the text-decoration invalid. In addition, highlighted is not a valid part of the font property, making it invalid. Therefore, this paragraph's font should be the UA default, and match the next paragraph. If this is not the case, then the font declaration is being improperly parsed.
